[patch] redraw more...

[Andre Poenitz]

The attached patch collapses 'REFRESH_AREA' and 'REFRESH_ROW' handling.
Goal is still simple two-phase drawing with 'redraw everything'.

I don't see any noticable sluggishness when jumping around in the
UserGuide (was to be expected I think)

Incidentally, this fixes the redraw bug when clicking to the right of a
displayed formula and typing there.

Ok?
